Precision medicine in immunoglobulin A nephropathy: still a journey ahead.

Nephrol Dial Transplant 2021 Jun;36(Supplement_2):24-30

Division of Nephrology and Clinical Immunology, RWTH Aachen University Hospital, Aachen, Germany.

Immunoglobulin A nephropathy (IgAN) is the most common primary glomerular disease worldwide and since its first description extensive research has identified a number of key central pathogenetic contributors, including genetic, immunological and environmental factors. Along with its multifaceted pathophysiology, the clinical presentation of IgAN varies, ranging from mild forms with only minor urinary findings and preserved renal function to cases that rapidly progress to end-stage renal disease. Because of this, early identification of patients at risk for a progressive course is urgently needed. Read More

Water calorimetry-basedfactors for Farmer-type ionization chambers in the SOBP of a carbon-ion beam.

Phys Med Biol 2021 Jun 21. Epub 2021 Jun 21.

Dosimetry for Radiotherapy, Physikalisch-Technische Bundesanstalt, Braunschweig, Niedersachsen, GERMANY.

The dosimetry of carbon-ion beams based on calibrated ionization chambers still shows a significantly higher uncertainty compared to high-energy photon beams, a fact influenced mainly by the uncertainty of the correction factor for the beam quality. Due to a lack of experimental data,factors in carbon-ion beams used today are based on theoretical calculations whose standard uncertainty is three times higher than that of photon beams. To reduce their uncertainty, in this work,factors for two ionization chambers were determined experimentally by means of water calorimetry for the spread-out Bragg peak of a carbon-ion beam, these factors are presented here for the first time.

Brain variability in dynamic resting-state networks identified by fuzzy entropy: a scalp EEG study.

J Neural Eng 2021 Jun 21. Epub 2021 Jun 21.

University of Electronic Science and Technology of China, No.2006, Xiyuan Ave, West Hi-Tech Zone, Chengdu, 611731, CHINA.

Objective: Exploring the temporal variability in spatial topology during the resting state attracts growing interest and becomes increasingly useful to tackle the cognitive process of brain networks. In particular, the temporal brain dynamics during the resting state may be delineated and quantified aligning with cognitive performance, but few studies investigated the temporal variability in the electroencephalogram (EEG) network as well as its relationship with cognitive performance.

Approach: In this study, we proposed an EEG-based protocol to measure the nonlinear complexity of the dynamic resting-state network by applying the fuzzy entropy. Read More
